BACKGROUND OF THE INVENTION

The present invention relates to methods and apparatus for keeping anddisplaying photographic images. More particularly, the present inventionrelates to the storage of digital photographic images in portabledevices that may, for example, be carried in a wallet or purse.

Photographs, since their inception, have always had a special place insociety. They provide a means for capturing special moments and/orplaces in people's lives, or are utilized in commercial applications tobetter explain things where “a picture is worth a thousand words.” Intoday's society, the immense growth of digital photography and theInternet has caused explosion the storage and transmission ofphotographic images. For example, it is now common for pictures ofnewborn children to be displayed on a family website only hours afterthe birth has occurred. In other instances, family photographs areexchanged as e-mail attachments to family members in different parts ofthe world.

While the use of the Internet and digital images has made it easier todistribute photographic images, such techniques have not been able toaddress the problem of having photographs in one's possession at anyplace and at any time. For example, when a purse or wallet is open,there is typically one or more family photographs. The photos are oftenold and worn because they may simply be in a stack. In othercircumstances, one of the pictures may be displayed all of the timebehind a transparent piece of plastic, however, these windows alsoyellow and appear to lose some of their transparency over time.Moreover, every time the user wants to show the pictures to someoneelse, they must be pulled out of the purse or wallet. This results inadditional wear and tear on the pictures.

It should also be noted that pictures are commonly developed in largersizes than wallet size, such as, for example, four inches by six inches.When someone wants to keep a particular picture in their possession,they either cut the larger picture to fit the wallet, or they must takethe negative to a photo processor and have a wallet-sized print made. Inview of the difficulty in getting proper “wallet-sized” pictures, thepictures in the purse or wallet typically become quickly outdated, andoften are never replaced.

For at least the above reasons, it is an object of the present inventionto provide methods and apparatus that enable people to easily carrymultiple photographic images.

It is also an object of the present invention to provide methods andapparatus for storing and displaying photographic images in which theimages can easily be updated.

It is still a further object of the present invention to provide methodsand apparatus for storing and displaying a fixed set of photographicimages.

SUMMARY OF THE INVENTION

The above and other objects of the present invention are accomplished bythe methods and apparatus described herein in a portable electronicphoto album. The electronic photo album of the present inventionincludes a small, portable, flexible display unit, and a limited set ofbuttons or like devices for determining which image is shown on thedisplay. The display is preferably a somewhat flexible colorliquid-crystal display (LCD) that may be supported by a thin, hardshell. The device is small enough, and light enough to be carried in awallet or purse, and is substantially resistant to damage that may becaused, for example, by someone sitting on the wallet. Thus, it may bepreferable for the device to be approximately the size of a standardcredit card.

The portable photo album of the present invention may be downloadablefrom a computer using standard or specialized interface cables. It maybe preferable, for the convenience of the user, to utilize the sameinterface cable as is used with many digital cameras. For example,Hewlett Packard manufactures a standard nine-pin RS-232 interface cable,which may be used with many digital cameras, such as the HP PhotosmartC200 Digital Camera. The portable photo album may also be downloadeddirectly from a digital camera, from digital still images captured by avideo camera, or from image stored on conventional FLASH memory cards(that currently are in wide spread use with digital cameras). It shouldalso be noted that while digital images are what is being stored,conventional photographs may also be used, provided they are convertedto digital form by using, for example, a flat bed scanner.

In other embodiments of the present invention, digital images arepermanently preloaded and stored on the portable photo album—i.e., usersdo not have the ability to load pictures into the device. These imagesmay be, for example, photographs of a particular band, whereby theportable photo album would be sold to fans of that particular band astrading cards are traditionally sold. The applications for permanentlystored images are wide-ranging, and may include, for example, sportsteams, sports highlights, a new line of clothes offered by a particularretailer (in which case, the portable photo albums may be given away aspart of an advertising campaign), or a series of photos depictingchildren's characters or nursery rhymes.

Other applications of non-user loadable photo albums may include beingdirectly integrated with a credit card, whereby advertising would bedisplayed every time the card was used. In that case, card issuers, mayissue new cards more frequently than is currently done as advertiserschange. Additionally, if “smart chip” technology is utilized—smartchips, which are well known in the area of credit cards, are ultra-thinprocessors that are located on the face of a credit card. Informationmay be downloaded into these processors using, for example, bank machinekiosks. Under these circumstances, the credit card issuer could updatethe photo album advertising whenever the user utilizes one of thesekiosks.

One advantage of a permanently fixed photo album, is the possiblereduction in hardware requirements. Essentially, all that is needed ismemory to store the images, working memory that includes what is beingdisplayed, and processing circuitry that swaps pages from stored memoryto display memory. The processor need not be a microprocessor, butinstead could be a simple programmable logic device (PLD), such as thosemanufactured and sold by the Altera Corporation of San Jose, Calif.Moreover, the memory on the fixed photo albums can be optimized based onthe number and resolution of the images being stored, to reduce memorycosts.

Additional embodiments of the present invention may also include thestorage of video clips instead of digital still images. These clips maybe on the order of five to ten seconds, or more, whereby the length oftime of the clip is determined, once again, based on the resolution ofthe images being displayed. For example, parents might want to keep avideo clip of their child's first steps, assuming they were lucky enoughto have the video camera ready to capture the moment, in their pocket.An additional consideration for video clips is frame rate, whichcontributes to the smoothness of the displayed video. The video clipsmay be downloaded from a computer, just as described above with respectto still images, or they may be downloaded directly from a digital videocamera, or conventional video camera that includes the ability tocapture digital clips.

The portable photo albums of the present invention also may include theability to produce sound via micro or sub-micro electronic speakercomponents and audio chips. The integration of sound with still imagesand/or video clips may provide the users with advanced features, but thedevices themselves may be more expensive and/or heavier and bulkier thansilent photo albums. Such devices may be used, for example, as a singingbirthday card in which family photos are displayed, or a customizedbirthday card in which the images/video clips are taken directly fromthe birthday party itself.

DETAILED DESCRIPTION OF THE DRAWINGS

The methods and apparatus of the present invention for providing aportable system to store photographic images enable individuals to carrymultiple digital photographs in a compact device that can easily bestored on one's person. The device is preferably credit card-sized, andcontains enough memory store multiple images. Of course, persons skilledin the art will appreciate that the number of images that may be storedmay also vary depending on the resolution of the stored image, whichaffects the size of the electronic file corresponding to the image.

FIG. 1A shows a general representation of a portable device for storingone or more photographic images. Photocard 100, is preferably sized onthe order of a credit card, or other like device, so that it can easilyfit in existing wallets and purses. Photocard 100 includes a relativelyrigid case 102 that may be utilized to provide the support structure fordisplay 104. Case 102 should be rigid enough to protect display 104, butis preferably at least as flexible as a credit card so that it mayeasily be stored in a wallet without providing discomfort to the user.Display 104 is preferably a flexible liquid crystal display that canprovide high resolution color images. Display 104 should also beresilient enough that it can withstand the stress typically associatedwith in a wallet, such as, for example, being sat on for an entire day.

Photocard 100 also includes one or more buttons, such as index buttons106 and 108. As illustrated in FIG. 1A, button 106 is intended to allowa person to review digital images going backwards in sequence, whilebutton 108 is intended to allow a forward review of images. Personsskilled in the art will appreciate that, for example, to reduce cost andmanufacturing complexity, a single button may be utilized to sequencethrough the stored images. Additionally, photocard 100 may beimplemented without any physical buttons (in which case, buttons 106 and108 would simply not be present), and instead may be implemented withone or more sequence “virtual buttons” which appear on display 104 andare implemented in software, rather than hardware. Under thosecircumstances, display unit 104 would be a touch screen responsive totouch inputs from the user. Moreover, photocard 100 may also include amagnetic strip 132 (which is located on the reverse side of the housing,see, for example, FIG. 1C), as is found on credit cards, so thatphotocard 100 could be used as a credit card, whereby the displayedimages could be, for example, advertisements or promotions.

One of the advantages of photocard 100 is that it can fit inside apocket, wallet, or purse. Another advantage is that it is a dedicatedunit, constructed to simply display digital photographic or similarimages. Accordingly, hardware requirements for photocard 100 aresignificantly reduced over conventional electronic devices. For example,conventional electronic devices often require microprocessors or otheradvanced processing circuitry to perform various functions. Photocard100, on the other hand, only requires processing circuitry that simplymoves data in to and out of memory.

FIG. 1B shows an example of the circuitry that may be utilized toimplement photocard 100. The circuitry includes memory circuitry 120,processing circuitry 122, display memory 124, and display circuitry 126.Memory 120 is used to store the digital images. Data is downloaded toit, or uploaded from it, by processing circuitry 122 along a bus, as iswell known. The processing circuitry 122, takes blocks or pages of datafrom memory 120, that represent a digital image to be displayed ondisplay 104. The data is then loaded into display memory 124 byprocessing circuitry 122, and a signal is provided to the displaycircuitry 126 (which typically includes driver circuitry). Displaycircuitry 126 then displays the data stored in display memory 124 ondisplay 104.

The processing circuitry requirements of photocard 100 are significantlyreduced over conventional electronic devices because a majority of theprocessing is simply memory access. No processing of the digital imagesis performed by photocard 100. Accordingly, processing circuitry 122 maybe implemented using, for example, a programmable logic device (PLD),such as those sold by the Altera Corporation, or application specificintegrated circuits (ASICs).

ASICs, in particular, are integrated circuits that are designed toperform a specific function, as opposed to devices which may beprogrammed to perform a variety of functions. ASICs are substantiallyless expensive, and require substantially less supporting circuitry thanconventional processing circuitry. Moreover, persons skilled in the artwill appreciate that the present invention may be implemented using asingle memory instead of memories 120 and 124. Under thosecircumstances, the processing circuitry could simply be designed todisplay a the data from a given location upon startup. Then, additionalimages are displayed by simply incrementing, or decrementing, the memorylocation a single page.

FIG. 1C shows another embodiment of the present invention in photocard130. Photocard 130 may include everything previously described withrespect to photocard 100, and shown in FIG. 1A. Photocard 130, however,includes body portion 134, which is substantially similar in size to acredit card, except that a segment is missing from the backside of body134. The missing segment, as is shown in FIG. 1C, is filled in by amemory card 136, such as the FLASH memory cards currently utilized withmany digital cameras. As shown in FIG. 1C, FLASH memory card 136 hasbeen placed within the missing segment of body 134 so that the twoportions, when mated together, are approximately the size and width of acredit card. Alternately, if the memory portion, need be slightlythicker than a conventional credit card, the magnetic stripe portion ofbody 134 could still be the same size as a credit card so that magneticstripe 132 could be swiped using conventional credit card readers. FLASHmemory card 136 connects to the circuitry of photocard 130 via connector138 (shown as a dashed line to indicate that it is, when mated, withinbody 134).

One advantage of photocard 130 is that no downloading capability need beprovided. All photo processing and image storage would occur at thecomputer or digital camera (video or still), with the images to bedisplayed being loaded into the FLASH card. Photocard 130 need only havememory to display images, such as where images are paged from the FLASHcard into display memory, and the LCD displays what is in displaymemory. Alternately, the dedicated processing circuitry could beconfigured to display images directly from FLASH memory card 132, inwhich case photocard 130 would have no memory at all. For shipping,storage, and carrying when no images are available, a dummy plug (notshown) could be utilized that plugs into the same connector as connector138.

FIG. 2 shows an illustrative example of how a photocard 100 device couldbe used in an image processing system 200. In addition to photocard 100,FIG. 2 also shows a camera 202 and a computer 210. Camera 202 ispreferably a digital camera, however, conventional film cameras may alsobe used without departing from the spirit of the present invention.Camera 202 may include a built-in flash unit 204, or it may be utilized,with a conventional stand-alone flash unit (not shown). Computer 210 maybe any type of computer running any type of operating system (“OS”),such as the Macintosh™ OS or Windows™ OS. Computer 210 also includes amonitor 212, that is preferably a color monitor, as well as a keyboard(not shown) and cursor input system, such as a mouse (not shown).Computer 210 may also include a conventional scanner (not shown.), whichmay be used to scan conventional photographs for conversion into digitalimages.

Computer 210 includes software, besides the OS, that may be used tomanipulate digital images. One well known software application for thispurpose is, for example, Photoshop™ by Adobe. Digital image manipulationsoftware permits a user to perform tasks such as, cropping and rotationof digital images, as well, as image quality enhancements (such as theelimination of “red eye”). Moreover, these programs also typicallyprovide the user with the ability to alter the digital images by, forexample, placing one person's face on someone else's body. Anotherimportant feature of these programs is the ability to save the digitalimage in a different format and/or resolution than the image taken bycamera 202 or scanned by the scanner.

Digital image manipulation programs also typically include the abilityto provide add-on software. One such piece of add-on software that maybe provided in conjunction with the present invention is a softwareguide for manipulating images so that they may be best displayed onphotocard 100. For example, the add-on software may include the abilityto display a window on monitor 212 that displays exactly what wouldappear if the same image were displayed on photocard 100 on display 104,in exactly the same size. Additionally, the add-on software could alsoinform the user how much memory would be required for storage anddisplay of the digital image at varying resolutions and color quality.For example, it is well known that a digital image displayed in“millions of colors” takes up significantly more memory that an imagedisplayed in 16 or 256 colors. While photocard 100 can be provided withenough memory to display images at even the highest of resolutions, theamount of memory provided is directly tied to the overall cost of thedevice. Accordingly, some models may offer, for example, sixteenmegabytes of memory, while others may only offer four megabytes.

Camera 202 may be connected to computer 210 for downloading digitalpictures into computer 210 via a cable 214, which has a connector216,for connection to camera 202 (and an additional connector (notshown) for connection to computer 210. Also shown in FIG. 2 are dashedlines representing cable 214′ having connector 216′. The dashed linesare intended to indicate that the cable used to connect camera 202 tocomputer 210 may in fact he the same cable that also connected photocard100 to computer 210. While such a configuration may be preferable, it isnot required to practice the present invention. One of the advantages ofhaving a single cable that connects to both camera 202 and photocard 100is the ability to leave the single cable connected to computer 210,regardless of what is being connect to it. As is well, known, often,computers have a limited number of I/O ports that cables can beconnected to. Thus, the use of a common cable and interface for both thecamera and photocard eliminates the undesirable requirement ofconstantly having to gain access to the back of computer 210 forreconfiguration of the cables.

Use of system 200 is described with respect to the flow diagram shown inFIG. 3. Initial step 302 for the use of image processing system 200 isthat one or more digital images are obtained. These images may beobtained via a camera such as camera 202 shown in FIG. 2. If the cameraused is a digital camera, then the photographs are already in digitalformat, and the process may continue. If, however, the photographs weretaken with a conventional camera, the images must be digitized. This canbe done in many known ways. For example, the standard photograph may bescanned using a conventional flat bed scanner and scanner software.Alternately, the film may be sent to a photoprocessor such as Kodak™,who offers individuals the ability to receive their photographs inseveral digital formats, such as CD-rom, conventional floppy disks, andas downloadable files on the Internet. Under any of those circumstances,the image is new available in a digital format.

The second step 304 is that the digital image is loaded into computer210, via, for example, cable 214. While the present invention includesthis step, persons skilled in the art will appreciate that individualsmay also load images directly from a digital still or video camera intophotocard 100. The elimination of the computer, however, may reduce thequality of the images displayed on photocard 100. Once the digitalimages are loaded into computer 210, they may be manipulated in step 306to further enhance the images that are to be displayed on photocard 100.For example, the image may be cropped and the number of colors reducedso that an increased number of images may be loaded into photocard 100,based on the fixed memory of the device.

Once the images have been manipulated, a program may be run from thecomputer that, in a step 308, loads the images into photocard 100,either sequentially, or in a particular order that may be set up by auser through software located on computer 210. Another alternate methodof transferring images into photocard 100 may be through the use ofinfrared I/O port 112 (shown as a dashed box, indicating that this maybe optionally added to photocard 100, as illustrated in FIG. 1A).Computers and/or digital cameras could also include infrared I/O portsso that digital images can simply be “beamed” from one device toanother.

FIG. 4 shows an alternate embodiment of the present invention inphotocard wallet 400. Photocard wallet 400 includes a body 401 that maybe formed of a material such a leather into a three-fold configuration(as shown) or other configurations, such as a two-fold (not shown).Wallet 400 includes four sections, which are labeled sections 402, 404,406, and 408. Section 402 refers to the area in the wallet where moneyis usually located. Sections 406 and 408 are conventional walletsections in that they may include, for example, slots 410 which areconfigured to carry materials such as credit cards 412. Built intosection 404, however, is photocard 100 which can display digitalphotographic images. Persons skilled in the an will appreciate that forconvenience and clarity, while the previous discussion of photocard 100is equally applicable with respect to wallet 400, the photocard actuallyplaced within wallet 400, may be different than that previouslydescribed. For example, paging switches 106 and 108 may be located in adifferent location so that they are aligned with wallet 400 when it isopen as shown in FIG. 4.

Persons skilled in the art will thus appreciate that the presentinvention can be practiced by other than the described embodiments,which are presented for purposes of illustration and not of limitation,and the present invention is limited only by the claims which follow.
